Use form data to submit query

Hi all, I recently ran into an issue with long queries (requesting a lot of fields) where the URI that is being constructed gets too long and due to the “q=” parameter that has more than 64000 characters the request is rejected (“URI too long”).

Though I admit that maybe that type of query is questionable, I found out that InfluxDB also reads the query parameter from multipart form data (see https://github.com/influxdata/influxdb/commit/f58a50c231afd6ee775ce213461c7c0043cd724f)

With the following code I was able to successfully submit a longer query to InfluxDB:

HttpClient client = new HttpClient();
MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(new StringContent("..."), "u");
form.Add(new StringContent("..."), "p");
form.Add(new StringContent(reallyLargeQuery), "q");
string url = $"http://localhost:8086/query?db={this.database}";

client.PostAsync(url, form)

Would that be something that could be changed in this client?

Deployed v8.0.1, all should be fine now. I tested both net461 and netcore2.0 and all tests now pass for both targets. Let me know. 😃

cheers
